SAFETY-CATCH FOR PINS.

Application filed December 1, 1915. Serial No. 64,570.

To all "LUILOWL it may concern:

Be it known that I, CHARLOTTE F. VVEsT, a citizen of the United States,residing at 1721 Champlain avenue, Chicago, in the county of Cook andState of Illinois, have invented a new and useful Improvement inSafety-Catches for Pins, of which the following is a specification.

My invention relates to improvements in catch devices for the pinportions of socalled belt-pins, brooches, breast-pins and other articlesof this general character employing a pin held at one end cooperating atits pointed end with a guard or catch with which it releasably engages;and my object is to provide novel and simple improvements in catchdevices as hitherto provided, whereby the pins will be prevented fromaccidentally disengaging from the cooperating catch devices, but will becapable of ready disengagement therefrom by the user. and which willminimize danger of tearing laces or other fine fabrics to which the pinsare applied.

Referring to the accompanying drawing Figure 1 is a perspective view ofa so-called belt-pin, with a catch device for the pm made in accordancewith my invention. Fig. 2 is an enlarged sectional view taken at theline 2 on Fig. 1 and viewed in the direction of the arrow. Fig. 3 is abroken sectional view taken at the line 3 on Fig. 2 and viewed in thedirection of the arrow; Figs. 4: to 7 inclusive, are views similartoFig. 2 of some of the other forms in which my invention may be provided;and Fig. 8, a view like Fig. 2 of still another modification.

Referring to Figs. 1, 2 and 3, the body of the belt-pin is representedat 8 and the pin portion thereof at 9, the pin 9 being pivoted to therear face of the body portion 8 at lugs 10 on the latter as indicated at11. The pointed end of the pin 9 cooperates with a safety catch devicerepresented at 12 which is made from a strip of metal of any desiredwidth, bent into a. form resembling in general an open fiat spiral, thesections or sides of which represented at 13 to 17 inclusive extendingat angles to each other as represented. The space between the sections15, 16 and 17 forms a seat for the pointed end of the pin 9, whichlatter is prevented from becoming accidentally disengaged from the catchdevice by the section 17 thereof, the relatively sharp angles at thejunctures of adjacent ones of the side sections forming Specification ofLetters Patent.

the guard device, serving, by the abutment surfaces thus provided forthe pin, to reduce to the minimum danger of accidental disengagement ofthe pin 9 from the catch device.

The side of the catch device 12 beyond that nearest the pivot 11 of thepin is, by preference, closed tb prevent damage to the goods to whichthe pin is applied, especially if it be lace or other relatively finefabric. This may be accomplished in any suitable way as by soldering orotherwise securing a plate such as that represented at 18, to the catchdevice, to extend across one of its open sides as represented in Figs. 2and 3.

The idea as explained of the construction illustrated in Figs. 1, 2 and3 is carried out in the modifications shown in Figs. 1, 5, 6 and 7, butis somewhat amplified however. In Fig. l the convolutions of the catchdevice are of a greater number than in the case of the constructionshown in Fig. l, the end of the section 17 having an added convolutionwhich may be curved or extend at an angle to the section 17 or may beformed of two angularly disposed sections represented at 19 and 20,these sections furnishing added security against accidentaldisengagement of the pin 9 from the catch device.

In the construction shown in Fig. 5 the sections forming theconvolutions of the guard device are arranged at such angles as toproduce a spiral structure of general. triangular form, the angles ofwhich are of such degrees that the abutments for the pin 9 at thejunctures of adjacent sections will serve effectually to prevent the pinfrom disengaging from the guard device.

In Fig. 6 I have illustrated a modification which exhibits a featurewhich may be employed in any one of the constructions shown in thedrawing. It consists in roughening or corrugating the surfaces of theguard device with which the pin 9 may come in contact when the pinengages the guard device. The roughened surfaces are inclicated at 21and as will be manifest serve to further minimize danger of disengagement of the pin from the catch device.

In the construction shown in Fig. 7 I have shown my invention asembodied in a device which combines a more or less true spiral with aspiral of angular form. The true spiral portion is represented at 22,

this portion connecting With sections 23, 24, 25 and 26 Which aredisposed at angles to each other as represented to prevent accidentaldisengagement of the pin from the catch device.

In each of the constructions illustrated there is provided a pluralityof angles formed at the juncture of adjacent sections comprising theguard device. This feature is of advantage inasmuch as the pin-point incase of a stress on the structure tending to move the pin out ofengagement With the catch device, instead of being deflected in suchmovement to a position Which augments the danger of release, is heldprac' tically to a straight line movement Without deflection. If desiredthe various angles between the sections forming the catch-devices may beextended beyond the planes of the faces of these sections as shown ofthe construction illustrated in Fig. 8.

which my invention may be provided I do not Wish to be understood asintending to limit it thereto, as it may take other forms.

hat I claim as new and desire to secure by Letters Patent is 1. A safetycatch for a pin comprising a member of general spiral form havingportions between its ends extending at angles to each other to presentrelatively sharp angular corners forming abutments for engagement withthe pin.

2. A safety catch for a pin comprising a member of general spiral formhaving portions between its ends extending at angles to each other ofapproximately ninety degrees or less to present relatively sharp angularcorners forming abutments for engagement With the pin.
